Two indoor air quality experts who are in China to work with athletes during the Beijing 2008 Olympic Games announced today that they have achieved up to 99% purity of the indoor air in their Beijing apartment. They installed specialized ultra-high efficiency air cleaning equipment to demonstrate that despite Beijing's reputation as having the world's worst air pollution problem -- it is possible to create healthy indoor environments anywhere in the world. They have outfitted their apartment with sophisticated air quality measuring equipment. Air purity specialists Frank Hammes and Kirk Sullivan have been in Beijing working with USA athletes to outfit their sleeping and training areas with ultra-high efficiency air cleaning systems. The project, called Operation Clean Air, is the first time ultra-high efficiency air cleaning has been used in a comprehensive plan to gain a performance advantage at an athletic event. All of the air cleaning systems used in Operation Clean Air are tested and certified to filter down to 0.003 microns, smaller than a virus, and more than 1,000 times smaller than the average particle size that is measured in PM 10 air pollution ratings. Hammes and Sullivan's original goal with Clean Air Apartment was to get the indoor air quality purity to above 95% on measurements 0.3 microns and larger. They themselves were surprised when they reached the 99% purity mark in individual rooms. Most air purifiers that people purchase at department stores improve air quality by less than 5%.
